Cellartis Human iPS Cell Line Kits contain human induced pluripotent stem (iPS) cells that are banked and characterized according to the highest industry standards, along with a starter set for the Cellartis DEF-CS Culture System. The iPS cells are adapted to the Cellartis DEF-CS Culture System, an easy-to-use, complete culture system for efficient iPS cell expansion in a feeder-free, defined environment. With this system, cells are maintained in an undifferentiated state with virtually no background differentiation, eliminating the need for cell selection. The highly reproducible nature of the Cellartis DEF-CS Culture System coupled with the stable high growth rate of these stem cell lines is ideal for mass production of cells. We currently offer multiple cell lines derived from different donors.
